Installation
Add this line to your application's Gemfile:
gem 'the_toy'
And then execute:
$ bundle
Or install it yourself as:
$ gem install the_toy
Usage
space = TheToy::Space.new # creates 5x5 square board
robot1 = TheToy::Robot.new(<nickname>) # Create robot that uderstand commands
robot2 = TheToy::Robot.new(<nickname>) # Create robot that uderstand commands
space.add_agent(robot1) # Syncronize robot with space
space.add_agent(robot2) # Syncronize robot with space
robot1.execute('PLACE 3,4,NORTH') # Place robot
robot2.execute('PLACE 2,1,SOUTH') # Place robot
space.print_map # See results
Description
The application is a simulation of a toy robot moving on a square tabletop, of dimensions 5 units x 5 units. There are no other obstructions on the table surface. The robot is free to roam around the surface of the table, but must be prevented from falling to destruction. Any movement that would result in the robot falling from the table must be prevented, however further valid movement commands must still be allowed.
Application can read in commands of the following form
PLACE X,Y,F
MOVE
LEFT
RIGHT
REPORT
PLACE
will put the toy robot on the table in positionX,Y
and facingNORTH
,SOUTH
,EAST
orWEST
.- The origin (0,0) can be considered to be the
SOUTH WEST
most corner. - The first valid command to the robot is a
PLACE
command, after that, any sequence of commands may be issued, in any order, including anotherPLACE
command. The application should discard all commands in the sequence until a validPLACE
command has been executed. MOVE
will move the toy robot one unit forward in the direction it is currently facing.LEFT
andRIGHT
will rotate the robot 90 degrees in the specified direction without changing the position of the robot.REPORT
will announce theX,Y and F
of the robot. This can be in any form, but standard output is sufficient.- A robot that is not on the table can choose the ignore the
MOVE
,LEFT
,RIGHT
andREPORT
commands. - Input can be from a file, or from standard input, as the developer chooses.
- Provide test data to exercise the application.
Constraints:
The toy robot must not fall off the table during movement. This also includes the initial placement of the toy robot. Any move that would cause the robot to fall must be ignored.
Example Input and Output:
- a)
PLACE 0,0,NORTH
MOVE
REPORT
Output: 0,1,NORTH
- b)
PLACE 0,0,NORTH
LEFT
REPORT
Output: 0,0,WEST
- c)
PLACE 1,2,EAST

Output: 3,3,NORTH
